WebGL build not showing new gameObjects

Hi, I have made a webGL build for something that works fine in a standalone build, but the webGL build doesn't show the gameObjects that I instantiate at runtime. When the application starts, I instantiate a number of game objects (512) whose scale I update at each frame (they're in an array of GameObjects and I loop through it in the Update method). I have no problems in the editor or in the standalone build, but in the webGL build the gameObjects are just not there. Does anyone know what might be causing this issue? Thanks
